Faster colonoscope withdrawal time without impaired detection using EndoRings

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Devices

Background:

• Mucosal exposure devices enhance polyp detection during colonoscopy.
• EndoRings are a type of mucosal exposure device evaluated in this study.

Purpose of the Study:

• To evaluate the impact of EndoRings on adenoma detection and procedure times in colonoscopies.
• To compare colonoscopies performed with and without EndoRings.

Main Methods:

• A university practice conducted a trial with 14 endoscopists using EndoRings.
• Colonoscopy procedures with EndoRings were compared to age- and indication-matched procedures without the device.

Main Results:

• The adenoma detection rate was 44% with EndoRings versus 39% without (P=0.39).
• Mean adenomas per colonoscopy were 1.2 with EndoRings versus 0.9 without (P=0.055).
• Mean withdrawal time was significantly faster with EndoRings (12.2 minutes) compared to conventional colonoscopy (16.1 minutes, P=0.0005).

Conclusions:

• EndoRings may facilitate faster withdrawal times during colonoscopy.
• The use of EndoRings did not compromise adenoma detection rates.
• Prospective trials focusing on procedure times are warranted for mucosal exposure devices.
